Reddish precipitate of Mercuric iodide and clear solution of Potassium chloride is produced
Hayem's solution. This is an isotonic fluid which consists of the folIowing constituents (in g/100 ml):sodium chloride 0.5, sodium sulphate 2.5 and mercuric chloride 0.25. The sodium sulphate discourages clumping of the erythrocytes and the mercuric chloride is a preservative.
nothing
titrate with mercuric nitrate solution
Mercuric or mercury II chloride is HgCl2
hayem solution contains: sodium chloride 0.5%, sodium sulphate 2.5% and mercuric chloride 0.25%. The sodium sulphate discourages clumping of the erythrocytes and the mercuric chloride is a preservation
Mercuric Chloride or Mercury(II) Chloride
Mercuric chloride is a soluble salt of mercury. The mercuric ions in solution interferes with vital enzymes in the cell membrane and cytoplasm of microbes. Unfortunately it is also poisonous to mammalian cells including human cells. It has largely been replaced by safer disinfectants.
Because mercuric chloride is a covalent compound and is not an ionic compound. Only ionic compounds give chromyl chloride test
Assuming you want 0.1% weigh/volume, you dissolve 0.1 g mercuric chloride in 100 ml of solution. So, you would weigh out 0.1 g (100 mg) of solid and dissolve in enough solvent to make a final volume of 100 ml.
Hayem's solution contain Mercuric chloride, sodium sulphate, sodium chloride and distilled water. It dissolves WBCs, dilutes RBCs and provides an isotonic environment for RBCs.
Mercuric amidochloride is obtained by the reaction between ammonia and mercuric chloride.
